NICOLAS LO'UKITSCH POUSGHKAREFF, OF MOSOOXV, RUSSIA.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 323,594, dated Augusta, 1885.

Application filed February 18. 1884.

To all whom, it may concern.-

POUSOHKAREFF, a subject of the Czar of Bussia, and a resident of Moscow,Russia, have invented certain Improvements in Vapor- ,urners, of whichthe following is a specification.

My invention relates to that class of burners employed in vaporizing andburning volatile hydrocarbons for illuminating purposes, the objectbeing to produce a simple and inexpensive burner that will effect a moreperi'ect combustion of the carbon than most burners of this character,and at the same time be safe from explosion and elegant in appearance.

The novel features of my invention will be hereinafter set forth, andparticularly defined in the claims.

In the drawings,which serve to illustrate my invention, Figure l is avertical section taken in the plane of the axis of the burner, the viewalso showing the reservoir in section. This figure shows the reservoirset in the wall and the burner arranged as a wall-bracket. Fig. 2 is anaxial section of a modified form of my burner. Fig. 3shows threevarieties of perforated burnertipawhich will be hereinafter de scribed.Fig. 4 shows awire I employ for inserting-the wick. Fig. 5 gives twoviews of the sliding ring, its stem, and its conductingspurs on a largerscale than the same are shown in Fig. 2. The function of this devicewill be hereinafter explained. Fig. 6 isa view illustrating, on asmaller scale,the arrangement of several of my burners in a cluster, allthe burners being supplied from one reservoir.

Referring to Fig. l, A is the reservoir for supplying the burner withthe necessary liquid hydrocarbon as benzine, for example. This reservoiris set or embedded either wholly or partially in the wall B, in order togive it a firm support and enable it to sustain the burners, to betterprotect it against accident from fire or other causes, and to conceal itfrom sight for obvious esthetic reasons.

0 is the pipe which conveys the liquid from and to the reservoir. Forconveniencein shifting the burner from side to side and to and from thewall, I prefer to joint the pipe 0, as at a a, in a manner similar tothat in which ,folded at its middle.

(No model.)

gas-brackets are jointed. The pipe 0 connects with the cup-likesubstantially-imperforatc base D of the burner, which may be ofporcelain or other similar material.

Fixed in base D is a metal holder, E, which rises a little above thelevel of the top of the reservoir A, and which is exteriorlyscrewthreaded at its top.

F is the wick-tube, which in this case is open at the top and which isprovided with an internally screw threaded flange collar, 1). adapted toscrew onto the upper end of the holder E when the wicktubeis insertedtherein, as shown.

G is the perforated burner-tip, which is in the form of a cap, and ismade to fit tightly upon the upper end of the wick-tube. This tip Iprefer to make of silver or some other metal possessing greatconductivity, and I provide it with one or more projections or spurs, c,also preferably of silver, which are in contact with the flame or underits influence, and conduct heat to the top, for reasons that will bemore fully described hereinafter. H is the wick, which may be of anysubstance usually employed for raising liquids by capillary force. Inthe present case I have shown the wick This wick I insert by means of awire, (I, (see Fig. 4,) having abranch bent at right angles at its end,which branch is inserted in the bight of the wick and the whole pushedinto the position shown. The wire d is allowed to remain in place in thewicktubc.

I is a tubular exterior envelope, which fits substantially air-tight ina socket in the base D, and rises nearly to the top of the burnertip G,as shown. This envelopeI usually make of opalescent or white glass orporcelain, to imitate a candle; but this is not essential. Its functionis to cut off the air from the burner and prevent an upward draft of airaround the burner-tip, which draft tends to cool the generatingchamber0, and make the flame smoky from excess of uncombined carbon particles.

I will now point out the mode of filling and using my burner.

The envelope I and the wick-tube are removed, the latter by unscrewingZ. The reservoir A is filled by pouring the liquid in at the open upperend of holder E until theliquid in same stands at about thelevel of thedotted line :0, which shows that the reservoir is about full. The airescapes from the reservoir at a "ery small aperture, 9, in the top ofsame, as the liquid flows in. \Vhile the lamp is consuming thehydrocarbon this aperture may be nearly stopped, as only air enough needenter to take the place of the liquid as fast as it is consumed. Thereservoir being filled, the Wick-tube is screwed and the outer envelope,I, set in place. The proper burner-tip, G, is now slipped onto thewick-tube and the burner ignited. The hydrocarbon vapor collects in thegenerating-chamber, and escapes at the perforations in tip G, when it isignited and burns. The heat of the flame is communicated to the walls ofchamber 6, and this heat serves to convert the vapor into a gas whichwill burn with a clear white flame. The chamber 0 being protectedagainst the colder air, and being made of a metal that may be readilyand highly heated, the heating of the vapors may be effected with verylittle flame, and the combustion will at all times approach very near toperfection.

I usually make the burner-tips removable, as shown, and provide severaltips, (see in Fig. 3,) differing from each other only in number ofperforations in them. One tip may be substituted for another in amoment, and thus the lamp be adapted to furnish atiny flame, as for anight lamp or flames of various sizes for various purposes. Theconductingspurs 0 may be made in various forms. In Fig. 3 I have shownthem of wire,with a loop formed at the free end of the wire.

The modification shown inFig. 2 differs in construction from the burnerjust described in these respects: The base D is inserted directly intoan ordinary lamp-reservoir, A, which is portable. The wick-tube F ispushed down through a bore in base D,which it fits snugly. This boreserves in some respects the same purpose as the holder E, the liquidbeing poured in at it preferably in filling the reservoir. Theburner-tip G is in this construction formed in one with the wick-tube,the top of the latter being closed and perforated. The chamber 6 is thusformed in the top of the wick-tube itself. The conducting-spurs c areattached to a band, 0, which closely embraces and slides on thewick-tube. This band I usually make of silver, as well as the spurs, asits function is in part to convey heat to the generating-chamber. Inorder that the band 0 may be conveniently adjusted up and down, I attachto it a wire-stem, h, which passes out through a hole in the base D,which hole it fits snugly and is provided with abranch bent on it, asshown, so that the stem may be conveniently manipulated. Thisdevice,which is shown on a larger scale in Fig. 5, is designed toregulate the size of the flame.

The conducting spur or spurs may be attached directly to the top of thewick-tube, where no cap Gris employed. When such caps are used, the sizeof the flame may be readily varied from that of a night light to oneequal to fifteen stearine candles, and by varying the position of theperforations, the form of the flame may be varied, producing flames of around shape, fan shape, sheaf shape, 850. The perforations in theburner-tip may also take the form of a slit.

I make no claim herein to the reservoir, nor the removable burner-tips,nor the wire for inserting the wicks, nor to the vaporizingchamber onthe wick-tube, nor to the conductors 0, nor, broadly, to a closeexterior envelope. Some of these features are not new with me, and someform no part of my present application; but

What I do claim is- 1. The combination, in a vapor burner wherein a wickis employed, of the close or imperforate base D, the imperforate andremovable cylindrical envelope I, mounted in base D, and the wick-tubeF, mounted in said base D inside the envelope I, and provided with agenerating-chamber, 6, above the wick, the said envelope 1 extending upnearly to the top of the wick-tube, substantially as and for thepurposes set forth. I

2. The combination, in a vaporburner, of the close or imperforate baseD, the imperforate outer envelope, I, mounted in said base D, thetubular holder E, fixed in said base D, the wick-tube F, provided with ageneratingchamber e, and the screw-threaded flanged collar b, fixed onthe wick-tube, constructed to fit over and arranged to screw onto thescrewthreaded top of the holder E, substantially as described.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing \Vi tn esses:

N. TSOHEKALOFF, L. Voss.
